Neural correlates of spatial orienting in the human superior colliculus.
A natural visual scene contains more information than the visual system has the capacity to simultaneously process, requiring specific items to be selected for detailed analysis at the expense of others. Such selection and inhibition are fundamental in guiding search behavior, but the neural basis of these mechanisms remains unclear. Abruptly appearing visual items can automatically capture att...
متن کاملActivity in the superior colliculus reflects dynamic interactions between voluntary and involuntary influences on orienting behaviour.
Performance in a behavioural task can be influenced by both bottom-up and top-down processes such as stimulus modality and prior probability. Here, we exploited differences in behavioural strategy to explore the role of the intermediate and deep layers of the superior colliculus (dSC) in covert orienting. Two monkeys were trained on a predictive cued-saccade task in which the cue predicted the ...
متن کاملAuditory orienting and detection in rats following lesions of the superior colliculus.
Rats were trained to run towards a lighted target following either bilateral lesions of the superior colliculus (SC) or control lesions of the overlying cortex. At 4 months post-surgery, the animals were tested for the disruptive effects of an auditory tone. An increase in running times was found in both groups, attributable to frequent freezing reactions in all animals. However, only the contr...

encountering each other on the migration south. But the new research reports results from six sea-floor acoustic recorders placed in the western George’s Bank off Cape Cod deployed in two triangular arrays each of three devices. The recorders were placed around 3 kilometres apart in the triangular array and the centre of two sets were 18.4 kms apart. Based upon the detection of song from one wh...
متن کاملSuperior Colliculus Does Play Dice
Random is not a word often used in describing nervous system organization and its development. Yet, in this issue of Neuron, Owens et al. (2015) identify stochastic interactions of molecular and activity-dependent forces that can produce heterogeneous retinocollicular maps.
